(DEACTIVATED)
ANNUAL REPORT NO. 25 General Electric Company has maintained the ESADA Vallecitos Experimental Superheat Reactor (EZESR) in a deactivated status under the authority of r
Amendment No. 3 to License DR-10, Docket 50-183, issued June 11,.1976.

SUMMARY
The facility remains in essentially the same condition described in the.
twenty-fourth annual report.
Entry into the containment building was made for routine radiation surveys and a general check of conditions throughout l
the building. Radiation levels remain essentially anchanged.
i f
I II.
STATUS OF THE FACILITY Access to the containment building is controlled by the Facility Manager f
according to written procedures. The reactor vessel and head storage shield plugs, the wooden cover over the fuel storage pool, and the locked covers for the personnel.and equipment hatchways remain in place.

RADIATION AND CONTAMINATION I
Complete radiation and contamination' surveys of the facility indicate that-the levels remain low.
Survey results are tabulated in Table 1.
The radiation / contamination levels listed are representative but not necessarily maximum values.
